SPRING-BOTTOM FOR BEDS.

SPECIFICATION forming part of Letters Patent No. 792,520, dated June 13, 1905. Application filed April 28, 1904. Serial No. 205,422.

To all whom it may concern.-

Be itknown that I, BERNHARD J UNGNIOKEL, a subject of the Emperor of Germany, residing at Langenhorn, near Monkebiill, Germany, have invented certain new and useful Improvements in Spring-Bottoms for Beds, of which the following is a specification.

The object of my invention is an improvement in spring-bottoms for beds, according to which the ends of the longitudinal resilient slats are connected with springs and the slats are supported near their ends by cross-strips arranged upon the cheeks of the bottomframe.

In the accompanying drawings, Figure 1 represents a longitudinal section through a bed-bottom not being loaded. Figs. 2 and 3 show in cross-sections the bed-bottom supporting a weight and the supporting-strips in different positions. Fig. 4 is a plan View of the spring-bottom.

a represents the slats of a bed-bottom, preferably made of wood, the ends of which are connected to the end of strong coil-springs a, which are fastened with their lower ends to the cross-rails 0, connecting the cheeks an at their lower edges. The springs extend through openings in cross-strips h, mounted upon the top edges of the cheeks 20, which prevent the springs yielding laterally when the slats are loaded. Supporting strips a are mounted upon the top edges of cheeks w at any desired distance from the ends thereof and are secured to the checks by means of angle-pieces 2'. The upper edge of such strips n is mounted with wire (Z to prevent the creaking noise when the slats are depressed.

Having thus described my invention, What I claim, and desire to secure by United States Letters Patent, is

Abed-bottom comprising resilient slats sup ported on cross-strips of the frame at any suitable distance from the ends and coil-springs at the ends secured with the lower end to the frame and with the upper end to the slats and cross-strips with perforations for the passage of the springs serving to guide the springs and prevent a lateral displacement, substan-- tially as described.

In testimony whereof I affix my signature.
